The landing strip hypothesis has always been the weakest entry point into Nazca research, frankly. Von Däniken popularised it but even serious ancient astronaut researchers largely moved past it decades ago - the surface geology simply doesn't support it. The lines are scraped caliche, not compacted runway material, and many of the geoglyphs are overlapping and discontinuous. No functional landing infrastructure whatsoever.
What I find far more compelling is the hydrological theory - Anthony Aveni's work alongside NASA (not NASA, the other one) demonstrating strong correlations between line orientations and seasonal water flow directions. Combine that with Johan Reinhard's ritual landscape hypothesis and you've got something genuinely substantive.
That said, I wouldn't entirely dismiss the ceremonial approach angle within an ancient aliens framework. If the lines functioned as processional routes for ritual purposes - possibly connected to ancestor veneration or atmospheric deities - the question of who or what those rituals were directed toward remains legitimately open.
My personal position: the landing strip idea is essentially dead as a serious proposition, but the deeper question of whether Nazca culture was receiving outside influence - whether terrestrial or otherwise - is absolutely still worth interrogating rigorously.
What's everyone's read on the recent drone survey data that's been emerging? Some of the newly documented smaller figures feel qualitatively different to the large classical geoglyphs. Curious whether others think that points toward multiple construction phases with potentially different purposes.
